UCC3818D Description

Short technical summary and product information.

The UCC3818D from Texas Instruments is an integrated circuit designed for active power factor correction (PFC) preregulators. It controls a boost preregulator to achieve near-unity power factor by shaping the AC input line current waveform to match the AC input line voltage.

 

This device features average current mode control for stable, low distortion sinusoidal line current. It operates with a frequency range of 6 kHz to 220 kHz and an operating voltage range of 12 V to 17 V. The typical start-up current is 150 µA, and it includes over-voltage protection.

 

The UCC3818D is housed in a 16-SOIC package, suitable for surface mount applications. Its operating temperature range is 0°C to 70°C.

 

Key applications include PC power supplies, consumer electronics, lighting, and industrial power supplies, particularly those requiring compliance with IEC6100-3-2 standards for supplies less than 300 W.
